How was your day?

So I'm leaving for Lebanon tomorrow and my mom told me my relatives have surprises in store in me. She told me the day I get there, there's a supper where all my relatives come and see me. All of them easily means 40+ people, there for me. I'm getting stressed about that because I'm going to be so boring and shy unless I get really drunk. But then If I'm drunk I'm scared I'll accidentally out myself and then I die.

With 40 different people to ask questions, you shouldn't have to worry much about striking up conversations. SOMEONE will be able to do that. Probably better not to drink much if you can avoid it, at least until you're more comfortable around them.
